I need to start a batch using java and after a few seconds i need to stop the running batch file.
here is my code
try {
Process process=Runtime.getRuntime().exec("cmd /c start D:/test.bat");
Thread.sleep(20*1000);
process.destroy();
} catch (Exception e) {
e.printStackTrace();
}
my code failed to stop the batch file.
It isn't that simple since you have to kill an independent operating system process you have just started. Looks like How to find and kill running Win-Processes from within Java? might help you.
In short: you have to find the PID of a batch script (actually, of a cmd process running your batch script) and kill it using taskkill.
If the batch is running in cmd.exe using Java, run this
Process prClose = Runtime.getRuntime().exec("taskkill /im cmd.exe");
If you run a java or javaw on your .bat file, you need to terminate your batch file first:
Runtime.getRuntime().exec("taskkill /f /im jqs.exe") ;
Runtime.getRuntime().exec("taskkill /f /im javaw.exe") ;
Runtime.getRuntime().exec("taskkill /f /im java.exe") ;
And stop cmd(if needed)
Runtime.getRuntime().exec("taskkill /f /im cmd.exe") ;
Hope this help!
